Our 7 pound yorkie went into severe convulsions and tremors, so bad we rushed him into the Vets, On emeregncy.
A day later, having had his stomache cleaned and put on IV to flush his system, the Vets prognosis is that someone in our area used a chemical on their lawns to kill weeds and he walked on their lawn.
Professionals tag the lawns to let you know they have been sprayed, but DIY , you don't know they have applied Weed N' Feed.
The bags say, stay off or 48 hours, but I wonder how many people apply this stuff, then let their kids go play on the grass??
Our town is debating banning weed killer applications, a move I will now support, the rain washes this stuff into the waterways, eventually ends up in drinking water.
Dog is fine, but Parents and other pet owners, be aware, the chemicals spread on lawns is harmful.
